Concert Pharmaceuticals, Inc. (NASDAQ: CNCE) today reported financial results for the third quarter of 2022.

“With the THRIVE-AA clinical program completed and positive Phase 3 results in hand for deuruxolitinib in alopecia areata, we are well on our way to meeting our goal of submitting the NDA in the first half of 2023,” said Roger Tung, Ph.D., President and Chief Executive Officer of Concert Pharmaceuticals. “Given the promising clinical properties and potential best-in-class profile displayed by deuruxolitinib and the great needs of the alopecia areata patient community, we are well-positioned to emerge as a leader in the autoimmune dermatology field. All of our development and precommercial efforts are strongly positioning us to make the transition to being a commercially focused organization.”

Recent Highlights and Upcoming Milestones

Deuruxolitinib (CTP-543): An Investigational Treatment for Moderate to Severe Alopecia Areata

• Deuruxolitinib EADV Late Breaking Presentation: In September 2022, Brett King, M.D., Department of Dermatology, Yale University School of Medicine, presented THRIVE-AA1 Phase 3 results in alopecia areata during the 31st European Academy of Dermatology and Venereology (EADV) Congress late breaking news session. To access the full presentation of the safety and efficacy findings from the THRIVE-AA1 study, visit Concert’s Scientific Presentation page on its website. Details of the presentation include:
  
  
  
  
  • SALT Scores for Scalp Regrowth. Data from the THRIVE‑AA1 study showed the ability of deuruxolitinib to achieve more stringent criteria for hair regrowth than was measured by the study’s primary endpoint of a Severity of Alopecia Tool (SALT) score of 20 or less (meaning 20 percent or less scalp hair loss) at Week 24. Specifically, 21 percent and 35 percent of patients in the deuruxolitinib 8 mg twice-daily and 12 mg twice-daily dose groups, respectively, achieved a SALT score of 10 or less at Week 24, compared to 0 percent of patients in the placebo group (p<0.0001). Also, the relative improvement in SALT score from baseline was significantly different for the 12 mg twice-daily dose group compared to placebo (p<0.001) as early as Week 4.
    
    
    
    
  • Eyebrow or Eyelash Regrowth. New data were presented showing that patients in the THRIVE‑AA1 study with loss of eyebrow or eyelash hair at baseline who were treated with deuruxolitinib had significant improvement compared to placebo starting as early as 12 weeks, which was the first time point measured, and continuing through the 24-week treatment period (p<0.001).

• Positive Phase 3 Results Reported for Deuruxolitinib THRIVE-AA2 Study. In August 2022, the Company reported positive topline results for its second deuruxolitinib Phase 3 clinical trial, THRIVE‑AA2. A statistically significant proportion of patients treated with either 8 mg twice-daily or 12 mg twice-daily of deuruxolitinib in the THRIVE-AA2 study experienced greater scalp regrowth compared to placebo. The proportion of patients achieving a SALT score of 20 or less at Week 24 was 33 percent in the 8 mg twice-daily dose group and 38 percent in the 12 mg twice-daily dose group, compared to 1 percent of patients in the placebo group. The treatment difference for both dose groups relative to placebo was statistically significant (p<0.0001). The safety profile seen with deuruxolitinib in THRIVE-AA2 was consistent with previous studies of CTP-543.

• Deuruxolitinib Phase 3 Presentation in Alopecia Areata at the World Congress for Hair Research. Dr. King will present additional results from the THRIVE-AA1 study during the 12th World Congress for Hair Research being held November 18-21, 2022 in Melbourne, Australia. The presentation will include additional analyses of hair regrowth based on disease severity and time course of disease.
